In the Windows operating system, a user account that is a member of the administrators group will not automatically have unrestricted full access to the operating system, thanks to the User Account Control system that has been implemented since Windows Vista. The purpose of the UAC restriction is to prevent malicious software from instantly making changes to any parts of the Windows operating system when it is launched. The User Account Control warning window will help to create an awareness to the user that a program from an unknown publisher wants to make changes to your computer.

As an example, the HOSTS file in Windows is used to map a hostname to an IP address and can be opened and viewed using a text editor such as Notepad. However, in order to save the changes made on the HOSTS file, Notepad must run as administrator or else you’ll get the error window saying “Access is denied.”

An older program that was compiled during the Windows XP era will also face problems if it requires changes in restricted areas because it doesn’t create a UAC prompt to elevate privileges when run. To solve this problem, you can manually run the program as administrator and here we have 10 different ways to do it.
